Polyurethane Insulated Panel

Lynxcool's Polyurethane Insulated Panels are manufactured using an advanced continuous dual-belt press production line, ensuring consistent product quality. Our insulation panels are composite building materials with a rigid polyurethane foam core. Under strictly controlled temperature and pressure, the foam is continuously injected and bonded between two metal panels, creating a structurally sound, load-bearing, highly insulating, and hygienic solution. We can supply these products directly to your project sites worldwide.

Our Products and Services

Our closed-cell polyurethane foam core has a thermal conductivity of only 0.022–0.024 W/m°C, one of the lowest in the industry. Therefore, you can build cold storage walls and ceilings only 100–200 mm thick, yet achieve insulation performance comparable to 300–400 mm thick mineral wool or polystyrene.

We offer a comprehensive selection of finishing materials to meet the unique needs of your project: galvanized steel, pre-coated steel, 304 or 316L stainless steel, and aluminum alloys—each material carefully selected to meet your hygiene, corrosion resistance, and aesthetic requirements.

Our standard panel widths and lengths cover virtually all cold storage construction options, while thicknesses from 50 mm to 250 mm accommodate a wide range of needs, from ambient temperature cleanrooms to -60°C ultra-low temperature freezers.

Technical Parameters

Application

With over 5 million square meters of polyurethane insulated panels installed globally, we have accumulated extensive experience and can provide customized solutions for a wide range of refrigeration and freezing applications. Whether it's a small modular cold storage facility or a large distribution center, we can meet your specific needs.

1. Cold Storage and Frozen Warehouses | -18°C to -35°C

Our polyurethane insulation panels are the standard material for commercial and industrial cold storage worldwide, with a recommended thickness of 100-200 mm, offering excellent insulation performance. Our cam-lock connection system ensures quick assembly and is suitable for various refrigeration environments.

2. Quick-Freezing Chambers and IQF Processing Rooms | -35°C to -45°C

Designed for low-temperature, high-humidity environments, the panels are 150-200 mm thick, providing excellent airtightness and thermal insulation to prevent heat penetration. Suitable for food processing companies, especially popular in the Asia-Pacific and Middle East regions.

3. Food Processing Cleanrooms and Hygienic Areas | 0°C to +15°C 

We offer panels that meet high hygiene standards, with a smooth, seamless surface resistant to hot water and chemical disinfectants. Designed to comply with food safety standards such as HACCP, BRC, and IFS, ensuring efficient cleaning.

4. Pharmaceuticals and Controlled Atmosphere Storage | +2°C to +25°C 

Our panels meet GMP specifications and are suitable for pharmaceutical cold storage and vaccine storage facilities. Using food-grade materials, they maintain stable temperatures and prevent condensation, ensuring the storage environment meets stringent regulatory requirements.

5. Modular Cold Storage and Pre-cooled Refrigerated Rooms | Suitable for Various Temperatures 

Our polyurethane insulation panels are suitable for prefabricated modular cold storage and portable cold storage rooms. They are quick to assemble and easily disassembled and relocated, perfectly meeting the needs of refrigeration facilities of different sizes and temperature requirements.

Why Choose Lynxcool?

Lynxcool offers high-performance Polyurethane Insulated Panels, drawing on over 20 years of manufacturing experience:

1. Continuous Dual-Belt Press Production

We use a continuous dual-belt press to ensure consistent foam quality. Unlike mass production, our process guarantees uniform foam density and a strong bond between the foam and the panel, and thermal conductivity testing is performed before shipment.

2. Closed-Cell Polyurethane Foam Core

Our closed-cell polyurethane foam core offers superior thermal and moisture resistance compared to EPS and mineral wool. It ensures durable insulation and structural integrity.

3. Cam-Lock Connection System

Factory-pre-assembled cam-lock connectors enable quick and precise assembly. Using food-grade silicone sealant, the system provides airtightness and vapor sealing, improving energy efficiency and reducing installation time.

4. Custom Finishes

We offer a variety of finish options, from polyester-coated steel sheets suitable for dry cold storage to stainless steel panels for harsh environments such as seafood processing. We can customize materials to your specific needs. 5. Floor Panels for Forklift Access

Our floor panels are designed for heavy-duty operations, featuring high-density polyurethane foam, thicker panels, and optional wire mesh reinforcement. They are slip-resistant, can withstand forklift loads, and ensure decades of durability.

6. Fire Resistance Options

Our Polyurethane Insulated Panels meet fire safety standards, using B2-grade polyurethane foam or optional B1-grade flame-retardant polyurethane foam and polyisocyanurate core material for enhanced fire resistance. We ensure compliance with relevant regulations without compromising thermal insulation performance.

FAQ

Q: What thickness of Polyurethane Insulated Panels do I need for my cold storage?

A: Panel thickness depends on the storage temperature and location:

+2°C to +5°C: 75–100 mm

−18°C: 120–150 mm

−35°C: 150–200 mm

−60°C: 200–250 mm

Hot climates require thicker panels. Provide your environmental and operating temperature data, and we will recommend the ideal thickness.

Q: What is the difference between PUF and PIR core panels?

A: PUF has a lower thermal conductivity, making it suitable for most cold storage. PIR offers better fire resistance (EU B/C class vs. PUF D–E class), ideal for fire-sensitive environments such as food retail and pharmaceuticals. Both panel types are available in the same sizes and finishes, and we can advise based on your needs.

Q: How are the panels joined on-site?

A: We use a cam-lock connection system—each panel comes pre-installed with male and female cam-lock profiles. Your construction team simply slides the panels into place, tightens the cam bolts, and applies food-grade silicone sealant for airtight sealing. No thermal bridging, and an experienced team can install 50-100 sqm daily.

Q: Can your panels be used for cold storage floors with forklift lanes?

A: Yes! We offer specialized floor panels with high-density polyurethane core (42-48 kg/m³) and a thicker surface (0.8-1.0 mm). With compression strength of ≥200 kPa (standard) or ≥300 kPa (heavy-duty), they are suitable for cold environments and forklift use. We calculate the best specifications based on your forklift’s axle load and wheel configuration.

Q: How do I clean and sanitize the Polyurethane Insulated Panels in food processing environments?

A: Our Polyurethane Insulated Panels are made with food-grade epoxy/PVDF coatings, designed for wet cleaning. The smooth, non-porous surface and concealed fasteners make it easy to clean with high-pressure hot water and standard faood industry disinfectants. We recommend inspecting the silicone seals every 3-5 years for any cracks.

Q: How long will your panels last?

A: With proper design, installation, and maintenance, our panels can last 25-40 years. Key factors:

Foam bonding: 10-year warranty for continuous press panels.

Panel selection: Choose the right panel for your environment.

Seal maintenance: Reapply silicone every 3-5 years.

Damage repair: Fix any forklift impact damage to prevent moisture ingress.
